The purpose of this study is to observe anatomical structure damage to the knee following a posterolateral corner injury and to describe a possible correlation between damaged structures and physical exam and radiographic findings. The physical exam techniques traditionally used to assess this injury include the varus stress test, the posterior drawer test, and the recurvatum test. In this study, we will use radiography to assess bony landmarks of the knee at rest and undergoing these tests, both before and after induction of a posterolateral corner injury in a cadaveric lower limb. This will better classify the structures damaged in varying degrees of posterolateral corner injury. The information will inform surgeons of expected damage to the bone and soft tissue structures of the knee, based on their physical exam and radiographic findings, in order to better prepare them for surgical repair of the joint. We also propose a novel mechanism by which to induce a posterolateral corner injury in cadaveric lower extremities, which can be used in future research.
